Problems solved by technology

[0005] The purpose of the present invention is that according to the existing luminescent water-based coatings, the amount of luminescent powder mixed in is large, resulting in high cost of raw materials, limiting the possibility of large-area decoration, complex luminescent pigment treatment process, reduced luminous performance, poor water resistance and durability, etc. The disadvantage is to provide a luminescent antibacterial water-based interior wall coating, which is low in cost and can be used for large-area decoration. The treatment process is simple and easy, with good luminous performance and good water resistance and durability. The antibacterial agent used will not cause problems such as discoloration and difficulty in dispersion.

Abstract

The invention discloses a luminous antibacterial aqueous inner wall coating and a preparation method and application thereof. The formula of the luminous antibacterial aqueous inner wall coating comprises the following components in part by weight: 30 to 60 parts of film-forming emulsion, 5 to 50 parts of luminous pigment, 5 to 40 parts of white pigment and filler, 0.5 to 15 parts of montmorillonoid filler, 0.1 to 5 parts of auxiliary agent and 5 to 15 parts of water. In the coating, aluminate long-afterglow luminous material subjected to surface treatment is used as the luminous pigment, pillared montmorillonite of loaded germicide quaternary phosphonium salt is used as antibacterial filler, and acrylic acid emulsion is used as base resin; and the multifunctional inner wall coating with good luminous, antibacterial and waterproof properties is obtained by adding the auxiliary agent. The coating is endowed with excellent luminous, antibacterial and mildew-proof properties based on the traditional inner wall coating; the preparation process is simple and feasible; the raw materials have low cost; and the coating can be used for large-area decoration of multiple places, combines the traditional decoration and emergency indication or weak light illumination functions, and has good industrialized value and broad application prospect.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to a luminous and antibacterial water-based interior wall coating and a preparation method and application thereof. Background technique [0002] Interior wall paint is one of the most widely used architectural paints in people's production and life. It has a wide variety, but its function is relatively single, and it is generally only used for simple interior wall decoration. And along with the raising that people require to the quality of life, people also put forward higher requirement to the function and the quality of interior wall coating. For example, Chinese patent CN 101531494 (application number 200910026294.4) discloses a preparation method of a scrub-resistant interior wall paint, which is to obtain an interior wall paint with good scrubbing performance by adding paste-like attapulgite clay. Chinese patent CN1982379 (application number 200510129955.8) disclose...
